Abstract: DISTRIBUTED CONTROL WITH MUTUAL SPARE SWITCH OVER CAPABILITY ABSTRACT OF THE DISCLOSURE          A distributed control system controlling a plurality of energize-to-start, energize-to-stop subprocesses is designed for on-line maintenance.  One or more of the process control computers (86) forming the distributed control system (86-100) can be removed from service and the input and output connections (130) thereto switched to another of the process control computers that remains on-line.  A bumpless transfer of control is achieved by reconstructing the status of the latches in the process control computer (86) removed from service that are history dependent and establishing that status in the latches of control circuits of the process control computer (96) assuming control.  The status that the history dependent latches should have is derived based upon the operating status of the subprocess at the time switching is complete.  Control functions dependent on the status of a latch are delayed until the reconstructed status of latches are complete.

Abstract: SHEET TRANSFER DEVICE AND METHOD                 Abstract of the Disclosure A sheet transfer device and method are disclosed for transferring sheets from a sheet stack to a utilization area such as a can pallet.  A base unit causes pivoting of a beam about a moveable pivot point so that a sheet picked up from the sheet stack is moved upwardly for a substantial distance and then pivoted to a point above a can pallet, after which the sheet is moved downwardly and deposited on the upwardly extending tops of a horizontal layer of cans on the can pallet.  Suction is supplied through a plurality of cups brought into engagement with the top sheet of a sheet stack to lift the top sheet from the stack, with the suction being terminated when the sheet is deposited on the can pallet to thereby release the sheet.  Upward movement of the sheet from the sheet stack and downward movement of the sheet toward the can pallet is effected by use of a cam follower engaging contoured cam guides to force displacement of the pivot point of a transfer beam as needed to obtain the desired movement toward and away from the can pallet and sheet stack.

Abstract: ABSTRACT          METHOD AND MOULD FOR A CAP WITH A TAMPER-EVIDENT BAND    The cap made in the mould of the invention comprises a skirt (14) attached to a band (20)  by frangible lugs (30).   The band has angularly spaced inward projections (21) for engaging over a bead on a container.   The cap can only be removed from the container by breaking the lugs leaving the band on the container.  The top faces of the  projections   (21)  which  engage  the  bead  are perpendicular to the axis of the cap to provide secure captivation.     This  is  produced  by  moulding  each projection between a mould core (40) and a slidable mould part (60).  The part (60) has a boss (61) defining a face (62) perpendicular to the cap axis for forming the top face of the projection.  The end face (63) of the boss is tapered outwardly from the perpendicular face (62)  and contacts a complementary face  (43) of the mould.   The lugs are formed between the bosses. Each projection (21) slides up the corresponding complementary face (43 ) as the stripper (70) strips the cap off the core, thereby preventing damage to the top face of the projection.

Abstract: Boat construction comprising identically curved longitudinal timbers 1 fitted on a rotational cylinder with the timbers 1 as curve shape. Fitting the timbers 1 at equal angular intervals means that identical laminate pieces can be used as planking 2 and with sufficiently high rigidity it is likewise possible to omit the cross- ribs. The timbers 1 preferably lie outside the planking 2 to protect this, when the boat is drawn up on the shore and at the same time counteract rolling. Assembly of the timbers 1 and the planking sheets 2 is undertaken by cutting a strip 6 from the timber 1 with a V-shaped line with the same angle as the sheets 1 and the strip 6, the parts being bonded together. The timbers 1 are preferably made from glue-laminated wood and the planking sheet 2 is watertight plywood. The individual parts are well-suited to mass production and export, it being possible to pack the parts together into a minimal consignment volume and assemble them in situ, as this requires no special tools. <IMAGE>

Abstract: A method and a plant for recovery of oil floating on water. The plant comprises a closed container (1), either submersible or semi-submersible, floating in the sea with its upper edge (5) at the boundary between oil and water. The mixture of oil and water floating on top of the container flows down through holes (10) in the upper surface or collecting table (4) of the container into the interior of the container. The mixture is then separated by settling and surplus water is discharged. A so called "calm bay" is formed above and in the immediate vicinity of the container by a collar (9) reaching above the surface and attached to the container, in order to gather the oil to a thick layer, so that less water flows down into the container. After settling, the oil is pumped over to a tanker. The container can be equipped with heating coils (13) in order to facilitate settling and enable pumping of the oil. A number of such containers can be combined to form a vessel.
